Description

This project aims to introduce a web-based prototype infrastructure in the form of a web application that provides researchers with seamless access to complete hydrological modeling functionality. This includes fetching the necessary geospatial and forcing data, preparing input files for a model by applying complex data preprocessing, running the model for a user defined watershed, and saving the results to the web. A typical hydrologic model setup involves a labor-intensive data preparation phase with workflows that may be difficult to reproduce. This paper introduces the web-based prototype that helps prepare input files, and run the model completely in the web. We discuss the design of the Tethys based front-end Graphical User Interface (GUI), and the HydroDS assisted backend workflow structures adopted to build the application. The paper demonstrates the features of the application that enables users to build and run hydrologic models. Given the possibility of huge data requirements slowing down the servers, we restrict our work to use only handful of data sources, and provide services that are only available for Western US. The TOPographic Kinematic APproximation and Integration (TOPKAPI) model serves as example of complete hydrologic modeling service, while Regional Hydro-Ecological Simulation System (RHESSys) and TOPNET model are included as examples of implementation of additional models into the framework.
